(SSH集成要点)
Struts,Spring与hibernate集成:
1、在工程中导入spring支持,导入的Jar包有：
* Spring 2.0 Core Libraries
* Spring 2.0 ORM/DAO/Hibernate3 Libraries
* Spring 2.0 AOP Libraries
* Spring 2.0 Web Libraries
2、在Spring配置文件中配置dataSource和SessionFactory,将hibernate配置与Spring配置整合在一起(可以删除hibernate.cfg.xml文件)；
3、导入数据库源所要使用的Jar包，如：DBCP所用的JAR包(commons-pool.jar)；
4、修改所有DAO的hibernate实现，因为Spring中提供了一个HibernateDAOSupport类，可以简化数据库的操作。使用所有DAO类都继承自该类；
5、将DAO采用依赖注入的方式注入到Biz中，再将Biz采用依赖注入的方式注入到Action中，在Spring配置文件中做相应配置；
6、将Spring与Struts集成：
1)在spring配置文件配置Action:将Biz注入到Action中；
2)修改Struts的配置文件：添加节点<controller processorClass="org.springframework.web.struts.DelegatingRequestProcessor" />
；
3)在web.xml文件中配置监听器以及web应用的初始化参数：
<!-- 向监听器类中传递初始化参数，以获取beanFactory对象 -->
   <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/applicationContext.xml /WEB-INF/applicationContext-beans.xml</param-value>
   </context-param>
 
   <!-- 使用监听器初始化Spring的beanFactory,并将其放入到Context中，在使用时将其取出，以获取IOC容器中的bean -->
   <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
   </listener>
7、为了解决应用中的中文乱码问题，我们可以不用自己开发过滤器类，Spring为我们提供了一个，只需要配置一下即可：
  <!-- 使用Spring中的过滤器解决中文乱码问题 -->
   <filter>
    <filter-name>characterEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
     <param-name>encoding</param-name>
     <param-value>UTF-8</param-value>
    </init-param>
   </filter>
 
   <filter-mapping>
    <filter-name>characterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
   </filter-mapping>
8、为了解决hibernate延迟加载的问题，使用Spring中提供的过滤器来解决，它能够让Session
在请求响应完成之后再关闭，配置方式如下：
<!-- 解决hibernate延迟加载带来的异常，配置过滤器使Session在请求完成之后再关闭 -->
   <filter>
    <filter-name>hibernate session manager filter</filter-name>
    <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
   </filter>
 
   <filter-mapping>
    <filter-name>hibernate session manager filter</filter-name>
    <url-pattern>/*</url-pattern>
   </filter-mapping>
9、因为OpenSessionInViewFilter在getSession的时候,会把获取回来的session的flush mode 设为FlushMode.NEVER。故进行insert、
update和delete操作时会产生异常：org.springframework.dao.InvalidDataAccessApiUsageException:
Write operations are not allowed in read-only mode (FlushMode.NEVER/MANUAL): Turn your Session into FlushMode.COMMIT/AUTO or remove 'readOnly' marker from transaction definition.
因此需要采用spring的事务声明,使方法受transaction控制:
<!-- 配置事务管理器 -->
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
  <property name="sessionFactory" ref="sessionFactory" />
</bean>

<!-- 配置Advice(事务的传播特性) -->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
  <tx:attributes>
   <tx:method name="add*" propagation="REQUIRED"/>
   <tx:method name="del*" propagation="REQUIRED"/>
   <tx:method name="update*" propagation="REQUIRED"/>
   <tx:method name="get*" propagation="SUPPORTS" read-only="true"/>
   <tx:method name="search*" propagation="SUPPORTS" read-only="true"/>
  </tx:attributes>
</tx:advice>

<!-- 配置事务管理器应用的范围 -->
<aop:config>
  <aop:pointcut id="affectMethods" expression="execution(* edu.accp.dao.hibImpl.*.*(..))"/>
  <aop:advisor advice-ref="txAdvice" pointcut-ref="affectMethods"/>
</aop:config>
10、 部署应用程序，启动服务器，如果发现异常：
java.lang.NoSuchMethodError:
org.objectweb.asm.ClassVisitor.visit(IILjava/lang/String;Ljava/lang/String;[Ljava/lang/String;Ljava/lang/String;)V
这是由于整合时Jar包的冲突引起的。

首选创建web.xml 主要是配置Struts的ActionServlet和Spring的字符过滤器

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.4" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee   http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
 
  <filter>
    <filter-name>CharacterEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>UTF-8</param-value>
    </init-param>
    <init-param>
      <param-name>forceEncoding</param-name>
      <param-value>true</param-value>
    </init-param>
  </filter>
 
  <filter-mapping>
    <filter-name>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
 
  <servlet>
    <servlet-name>action</servlet-name>
    <servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
    <init-param>
      <param-name>config</param-name>
      <param-value>/WEB-INF/struts/struts.xml</param-value>
    </init-param>
    <init-param>
      <param-name>debug</param-name>
      <param-value>3</param-value>
    </init-param>
    <init-param>
      <param-name>detail</param-name>
      <param-value>3</param-value>
    </init-param>
    <load-on-startup>0</load-on-startup>
  </servlet>
 
  <servlet-mapping>
    <servlet-name>action</servlet-name>
    <url-pattern>*.do</url-pattern>
  </servlet-mapping>
 
  <!-- session超时定义,单位为分钟 -->
  <session-config>
    <session-timeout>10</session-timeout>
  </session-config>
 
  <!-- 默认首页定义 -->
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>index.html</welcome-file>
  </welcome-file-list>
 
</web-app>

然后创建struts.xml(String配置文件) 要注意这里集成了Spring插件,把全部Spring配置文件注入到ContextLoaderPlugIn中

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts.apache.org/dtds/struts-config_1_2.dtd">

   <forward name="error" path="/error.jsp"/>
  </global-forwards>

  <action-mappings>
   <action path="/login"
     name="loginVO"
      type="org.springframework.web.struts.DelegatingActionProxy"
      parameter="action"
      scope="request">
      <forward name="login" path="/login.jsp"/>
      <forward name="index" path="/index.jsp"/>
    </action>
  </action-mappings>

  <!-- 集成Spring插件 -->
  <plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
    <set-property property="contextConfigLocation" value="/WEB-INF/spring/*.xml" />

               <prop key="*">PROPAGATION_REQUIRED</prop>
       </props>
     </property>
    </bean>
</beans>

配置Action将Service注入到Action

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<!-- 配置Action，singleton属性设置为false表示不使用单例，每次都重新创建实例，避免并发问题，注入事务管理的Service -->
